4. Turn off Windows' Fast Startup feature

The Fast Startup feature in Windows 10 helps you restart your PC faster after shutting down. When enabled, it saves the operating system to a hibernation file to speed up the boot process. It's a handy feature to have on older systems, especially if your system takes a long time to reboot.

However, it also has some disadvantages. When Fast Startup is enabled, Windows will lock the installation drive. As a result, Windows may not recognize the operating system on a dual-boot configured system.
